This is very easy to dao. you just staple the cups together in the shape of container you are using and place cupcakes in them. I believe you use 5oz plastic cups. got mine at walmart. took a couple different walmarts to find though.

If any of you want shoot me a message with your email and I will send you a pdf I have had that combines a bunch of the tips and pictures I have gotten for doing these, I got the original instructions from a nice lady on the Wilton boards, but added to them and got a great tip to use those little portion cups vs regular cups
